I think this kind of issue involves DDG's AI. Google's is far superior in this respect. Heck, G has gotten me to things that I faintly remember but I know, without a shadow of doubt that I'd still be uncertain of 'that thing' I was trying to remember.

This is a search problem. I honestly don't see why DDG can't develop an AI that understands cultural and language contexts. Currently it doesn't but innovating this will take a lot of brain power, something DDG is lacking (when comparing the sheer #s of personnel focused on search).
